Tiny color graphic LCD w/controller?

  1. Hi,

    I need to build a quick and dirty prototype of an appliance that
    requires a small, low-resolution color LCD. I'm looking for an
    off-the-shelf module that includes a controller and video RAM so that
    I can interface it easily to an AVR. Resolution 80x60 would be enough,
    4:3 aspect ratio (or close to it) is mandatory. 2" diagonal or smaller
    is the size range I'm looking for. Four-level grayscale would probably
    be acceptable. The main thing is, I need to be able to buy it in a
    onesie for a one-time project.

    The Hantronix HDM1216C-2 is the closest thing I've found so far, but
    it's a non-stock item at Mouser and I haven't got a reply on the
    leadtime yet. Plus, it's 160x120 and that's more resolution than I

    Any other candidates people can suggest?
  2. Following up to myself:
    Immediately after I posted this, the customer emailed me to say that a
    grayscale first prototype would be acceptable too. So I expand the
    request to include a grayscale 1.8" or smaller graphic module, at
    least 64x64 pixels with 4 gray levels and on-board controller (COG or
    module, I don't care) :)

    How about the display out of this:

  4. Maybe this will work for you (and the price is right!)

    This doesn't meet your specs, but here it goes anyway,
    could be useful for other embedded projects:

    The Sega Dreamcast VMS/VMU ("Visual Memory
    System/Unit") has a 32x48 pixel LCD + CPU & 128K
    flash memory for around $25.
    (The display is probably 1 bit deep)

  6. Hi Jim,
    The LCD itself is great, but I'd need a controller.
    This is reverse-engineering the PVD disk format, not the hardware
    itself :( But thanks for the response, in any case.

    Have you looked at the screens in some of the newer phones ?

    couple of projects on avr freaks using nokia 7110 screens(96x64)

  8. Hi Robert,
    Very nice product, and the price is great - but it doesn't have a
    controller. It needs to be driven in realtime; I need a display module
    where I can just write the data once and have the LCD self-refresh.
    There aren't many modules like this available.
  9. Hmmm, you are right. This would be a mess to program in a hurry.

    Regards (and good luck)

    I just interfaced one these to my gate array board.
    Hardest part was building a pcb to deal with the fine traces
    of the 22 pin connector. The Verilog code to get it working was easy.

    The only problem is I could not get the led lamp to work. Even
    sacraficed my spare taking it apart to try and see how it was wired
    up. I could get the leds to light by applying power directly to them,
    but not at the connector.

    Still it is a cheap way to experiment with an lcd display.

    Colour Gameboy ?. Apparently Z80 processor and loads of info and
    projects on the web, like digital scopes etc...
